97 persons per public water point (83%)
But some gaps remain in under served, un-served, poor communities, difficult areas and Low coverage in arsenic affected, low water table and difficult areas).

Water Supply Coverage: Urban (June/07)

Pourashava & City corporation: 315
Piped Supply:100
Under Implementation: 68
Yet to undertake for piped supply:147
Coverage( towns having piped supply):31%

Sanitation (December/07):
  • Coverage in rural areas is 86.23 %

  • About 29% tube wells in those 271 Upazials are arsenic contaminated.
  • About 29 million people are exposed to arsenic contamination.q
  • About 8500 villages have more than 80% arsenic contaminated tube wells.
Problems and Constraints

Water supply:
  • Not enough perennial and protected surface water source.
  • Surface water sources are highly polluted mainly because of industrial and agricultural pollutants.
  • Contaminated surface water is difficult and expensive for treatment.
  • Lack of safe aquifer in some parts of the country.
  • Contamination of Ground water from arsenic, iron and salinity.
  • Lowering of Water Table
Sanitation
  • Urban sanitation is in acute condition with very insignificant investment.
  • Hard-Core Poor have no land to build a latrine.
  • Present technology for pit latrines is not suitable for high water table area.
  • Pit latrines are not suitable for densely populated area.
  • Densely populated area needs expensive sewer system.
  • Low priority on R&D activities on sanitation.q Low Private sector investment.
  • Donor assistance to urban sanitation is insignificant.
Others
  • Institutional weakness in both public and private sector.
  • Pourashavas are yet to be technically and financially capable for WSS management.
